Congressional Activity
Biogen Inc. - Common Stock (BIIB)
ARIA INTELLIGENCE BRIEF

Public disclosure records show six members of Congress have filed a combined 25 trades in this Health Care sector security between February 2021 and June 2026, with buying activity outpacing selling at 16 purchases against 9 sales. The most-active filers by disclosed trade count are Ro Khanna, Maria Salazar, Rob Bresnahan, and Gil Cisneros, and no bipartisan co-trading clusters are recorded for this name. The disclosure record does not surface any concentrated cross-party trading groupings, reflecting a relatively small and dispersed set of congressional filers. Separately, six executive-branch officials have disclosed eight transactions in the same security across the same general period, representing an overlap in independent public filings.

Signal Congress surfaces public disclosure data. This is not investment advice and does not imply wrongdoing.
